Grundles 

Grundles are brown cave-dwelling creatures from the My Little Pony movie. They look like monsters to most people, but, as they constantly reassure Baby Licketysplit and Spike the dragon, "Grundles good!" They are helpful, friendly creatures. Interestingly, Danny DeVito played the Grundle Leader in the movie.

Grundles not monsters! Grundles good!

Grundles 

Underpants, Underwear, be it Boxers, Briefs, Thongs, high rise, low rise, cotton, rayon, or polyester.

Grundles is actually short for grundlemires, as panties is short for underpants.

If you cut somebody off in traffic and they start flipping you off or shouting obscenities, simply say "Hey, don't get your grundles in a bundle, pal."
